Why is Schlecker in so much trouble?
A retail brand can be compared to a plant, it has to be nurtured! At any time if you just leave it to produce fruit (or profit) without the proper care (or investment) it will slowly, and then suddenly, die!
That is what is happening to Schlecker. The locations were always inconsistent, the store format is outdated, the uniqueness of the offer is hard to recognise, and the news clippings for the last 10 years were always weighted negative.
The probability that Schlecker can survive is low, the costs of putting things right are higher than the break-up value and the time needed to do it will not be graciously given by the competition.
